Abstract:
The outer solar system contains a large number of small bodies (known
as trans-Neptunian objects or TNOs) that exhibit diverse types of
dynamical behavior. The classification of bodies in this distant
region into dynamical classes-subpopulations that experience similar
orbital evolution-aids in our understanding of the structure and
formation of the solar system. In this work, we propose an updated
dynamical classification scheme for the outer solar system. This
approach includes the construction of a new (automated) method for
identifying mean motion resonances. We apply this algorithm to the
current data set of TNOs observed by the Dark Energy Survey (DES) and
present a working classification for all of the DES TNOs detected to
date. Our classification scheme yields 1 inner centaur, 19 outer
centaurs, 21 scattering disk objects, 47 detached TNOs, 48 securely
resonant objects, 7 resonant candidates, and 97 classical belt
objects. Among the scattering and detached objects, we detect 8 TNOs
with semimajor axes greater than 150au.
Description:
Dark Energy Survey (DES), is a nominal five year baseline optical
survey intended primarily for cosmological purposes. DES used the Dark
Energy Camera (DECam) on the 4m Blanco telescope at the Cerro Tololo
Inter-American Observatory in Chile. Its survey area subtended a total
of 5000square degrees of sky, which was tiled with two survey modes:
the Wide Survey, which imaged the full survey area roughly twice per
year to a limiting magnitude of r∼23.8 mag for single epoch exposures
in each of the grizY bands; and the Supernova Survey, which consisted
of 30°2 spread over 10 regions, each of which were imaged
roughly weekly in the griz bands. In this work, we present the
dynamical classification of 240 TNOs detected by the DES.
